Have TV Questions? Ask a TV Technician
I just tried that and no the screen is black no menu image
These symptoms would line up with the Inverters in the set not working properly, as the Power Supply and mainboard generate the voltages to the Inverter Board. So, you've had the same exact symptoms when you replaced both the supply, and the mainboard correct?
If so, and provided both boards you purchased are new, then you would need to purchase the inverter for your set, which is available at the link below:
ok so is this the board at the top of the screen connected with a ribbon cable? It dpoes not loon like it is very easy to get to. How do you change it?
Just letting you know the inverter board you recommended does not fit my tv. Turns out the back light inverter is built into the power supply board. So that was a waste of $30.
That is correct
No still the same. Vizro logo amber, turns white when power is applied but no back light.
Thats what I was afraid of. I guess I will try to sell the new boards I got and just scrap the rest. Thanks for your help.
